A standoff is typically threaded and used to secure a board in place, while a spacer is usually unthreaded and acts as a simple sleeve to maintain a specific distance.
Board Spacers & Standoffs Component Intelligence
Precision mechanical support for PCB stacking and chassis mounting.
What are Board Spacers & Standoffs components?
Board spacers and standoffs provide essential mechanical spacing between PCBs or between a board and a chassis. Selection depends on thread type, material conductivity, required standoff height, and the environmental stress of the final enclosure.
How to Choose Board Spacers & Standoffs Components
Selecting the right standoff requires balancing mechanical load, electrical isolation, and assembly speed.
Material Selection
Use nylon for electrical isolation, aluminum for weight reduction, or stainless steel for high-strength, corrosion-resistant applications.
Thread Configuration
Identify if you need male-female, female-female, or male-male configurations to match your mounting hole and screw requirements.
Height and Tolerance
Ensure the standoff length accounts for component height on the board and the required clearance for airflow or connectors.
Hex vs. Round
Hex standoffs allow for easy tightening with a wrench, whereas round standoffs are preferred for space-constrained or aesthetic designs.
Environmental Factors
Consider thermal expansion coefficients if the assembly will be exposed to extreme temperature cycling.
